Updates on inclusive charmed and bottomed meson decays from the lattice
arxiv(2024)
摘要
With the development of lattice QCD in recent years, a determination of decay
rates for inclusive semileptonic decays from lattice correlators now seems
viable. We report on the calculation of the inclusive semileptonic decay of the
D_s meson on the lattice. We simulate the D_s → X_sℓν_ℓ
process with Möbius domain-wall charm and strange quarks, whose masses were
approximately tuned to the physical values. We cover the whole kinematical
region. We present a general overview on how the inclusive decays are treated
on the lattice and discuss ongoing challenges, such as the estimation of
systematic errors and future prospects of the project.
